Though I see now that the only supported types are strings, floats, ints and vtk.vtkObject. In my case I would have been interested in QMouseEvent, since I read that QVTKWidget will use that as callData on the C++ side and was hoping the could have been true in Python (but perhaps it wouldn't have been due to other reasons..?).</div></div></div></div></blockquote><div><br></div></span><div>You're the first person who has asked, but yes, it would be possible to modify the Python wrappers to pass a Qt object as the callData.  If you're willing to try, or if you know someone who'd be willing, I'd be glad to provide assistance. The modifications would have to be done in vtkWrapPythonMethodDef.c. The wrapper API provides a method called SIPGetPointerFromObject() in vtkPythonUtil.h that is specifically made for getting a "void *" for a Qt object.</div></div></div></div></blockquote><div><br></div><div>Out of curiosity I looked into this a bit deeper, and it would be harder than I thought. It cannot be done without re-enabling at least some of the VTK SIP wrapper functionality that has been bit-rotting for the past few years. Of course, this is all very doable if someone is willing to do it.</div><div><br></div><div> - David</div></div></div></div>
